I noticed that tab traversal stopped working on iOS when #73440 was landed.
It seems to be that the control characters were excluded from the list of logical keys, and so they ended up being generated values.
This PR just adds "Enter" and "Tab" to the list for both macOS and iOS.
This fixes a problem where the character field of the RawKeyEvent was not being set at all for non-Android platforms.
I also updated the key maps, and corrected a problem with the Windows key map where the backquote character wasn't correctly mapped.
This standardizes the handling of nullability for the LogicalKeyboardKey.keyLabel and RawKeyEventData.keyLabel accessors so that they are non-nullable, but can be empty.
Before this change, the keyLabel could be either null or an empty string to indicate that there wasn't a label, which makes it harder to test for, since both need to be checked for. Since an empty string is sufficient, there is no need for it to be nullable.
Also, in raw_keyboard.dart, the web and Windows implementations wouldn't accept null values for parameters in the Map coming from the message, but tests were supplying null for some of them. This makes web and Windows creation of events match the other platforms, and makes the migration of tests to non-nullability easier.
This adds generation of some C++ keycode maps for various platforms.
This isn't meant for general use: it's so that the Flutter authors can keep the keycodes up to date with the Chromium and Android (and other) sources. It doesn't run continuously, it's only run occasionally (manually) to update the maps, because they don't change very often, and there is often manual work needed to make it function.
In this PR, I added output of various .cc files that write into an engine repo situated next to the flutter repo on disk. This is a starting point for implementing platform-side handling of key events.
* Update packages.
* Add many more global analyses.
* Catch trailing spaces and trailing newlines in all text files.
Before we were only checking newly added files, but that means we
missed some.
* Port the trailing spaces logic to work on Windows too.
* Correct all the files with trailing spaces and newlines.
* Refactor some of the dev/bots logic into a utils.dart library.
Notably, the "exit" and "print" shims for testing are now usable
from test.dart, analyze.dart, and run_command.dart.
* Add an "exitWithError" function that prints the red lines and
then exits. This is the preferred way to exit from test.dart,
analyze.dart, and run_command.dart.
* More consistency in the output of analyze.dart.
* Refactor analyze.dart to use the _allFiles file enumerating logic
more widely.
* Add some double-checking logic to the _allFiles logic to catch
cases where changes to that logic end up catching fewer files
than expected (helps prevent future false positives).
* Add a check to prevent new binary files from being added to
the repository. Grandfather in the binaries that we've already
added.
* Update all the dependencies (needed because we now import crypto in
dev/bots/analyze.dart).
* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
This adds support for the fn key on macOS. It adds it to the key mappings as a supplemental mapping that overwrites the one from the Chrome headers, since the chrome headers have a TODO, but no implementation of the key.
Also, ignore the fn key entirely on macOS. This is because On macOS laptop keyboards, the fn key is used to generate home/end and f1-f12, but it ALSO generates a separate down/up event for the fn key itself. Other platforms hide the fn key, and just produce the key that it is combined with, so to keep it possible to write cross platform code that looks at which keys are pressed, the fn key is ignored.
This updates the keyboard maps to use updated HID codes for game controller buttons (from Chrome), and to encode that GLFW "super" keys are what we call "meta" keys (i.e. Windows key or Command key).
This adds support for game controller buttons. It adds some supplemental USB HID codes that aren't available from the Chromium source code, and maps those on Android to the game pad buttons that Android supports. Other platforms are not supported yet.
This implements the keyboard shortcut handling and action invocation in order to provide a place in the infrastructure for keyboard events to trigger actions. This will allow binding of key events to actions like "move the focus to the next widget" and "activate button".
This adds a list of key synonyms for non-printable keyboard keys that appear in more than one place So keys like LogicalKeyboardKey.shiftLeft and LogicalKeyboardKey.shiftRight now can be mapped to just LogicalKeyboardKey.shift.
I also fixed a bug in the gen_keycodes tool where GLFW entries would get removed if they weren't parsed from the source on the web.
This re-lands the Focus changes in #30040. Correctness changes in routes.dart, and removes the automatic requesting of focus on reparent when there is no current focus, which caused undesirable selections.
Addresses #11344, #1608, #13264, and #1678Fixes#30084Fixes#26704
Implements focus traversal for desktop platforms, including re-implementing the existing focus manager and focus tree.
This implements a Focus widget that can be put into a widget tree to allow input focus to be given to a particular part of a widget tree.
It incorporates with the existing FocusScope and FocusNode infrastructure, and has minimal breakage to the API, although FocusScope.reparentIfNeeded is removed, replaced by a call to FocusAttachment.reparent(), so this is a breaking change:
FocusScopeNodes must now be attached to the focus tree using FocusScopeNode.attach, which takes a context and an optional onKey callback, and returns a FocusAttachment that should be kept by the widget that hosts the FocusScopeNode. This is necessary because of the need to make sure that the focus tree reflects the widget hierarchy.
Callers that used to call FocusScope(context).reparentIfNeeded in their build method will call reparent on a FocusAttachment instead, which they will obtain by calling FocusScopeNode.attach in their initState method. Widgets that own FocusNodes will need to call dispose on the focus node in their dispose method.

This converts all remaining "## Sample code" segments into snippets, and fixes
the snippet generator to handle multiple snippets in the same dartdoc block
properly.
I also generated, compiled, and ran each of the existing application samples,
and fixed them up to be more useful and/or just run without errors.
This PR fixes these problems with examples:
1. Switching tabs in a snippet now works if there is more than one snippet in
a single dartdoc block.
2. Generation of snippet code now works if there is more than one snippet.
3. Contrast of text and links in the code sample block has been improved to
recommended levels.
4. Added five new snippet templates, including a "freeform" template to make
it possible to show examples that need to change the app instantiation.
5. Fixed several examples to run properly, a couple by adding the "Scaffold"
widget to the template, a couple by just fixing their code.
6. Fixed visual look of some of the samples when they run by placing many
samples inside of a Scaffold.
7. In order to make it easier to run locally, changed the sample analyzer to
remove the contents of the supplied temp directory before running, since
having files that hang around is problematic (only a problem when running
locally with the `--temp` argument).
8. Added a `SampleCheckerException` class, and handle sample checking
exceptions more gracefully.
9. Deprecated the old "## Sample code" designation, and added enforcement for
the deprecation.
10. Removed unnecessary `new` from templates (although they never appeared in
the samples thanks to dartfmt, but still).

This adds support for logical and physical key information inside of RawKeyEvent. This allows developers to differentiate keys in a platform-agnostic way. They are able to tell the physical location of a key (PhysicalKeyboardKey) and a logical meaning of the key (LogicalKeyboardKey), as well as get notified of the character generated by the keypress. All of which is useful for handling keyboard shortcuts.
This PR builds on the previous PR (#27620) which generated the key code mappings and definitions.
This adds a keycode generator that incorporates input from the Chromium and Android source trees, as well as some local tables, to generate static constants for the LogicalKeyboardKey and PhysicalKeyboardKey classes, as well as mappings from each of the platforms we support so far (currently only Android and Fuchsia).
This code generator parses the input files, generates an intermediate data structure (`key_data.json`) that is checked in, and then generates the Dart sources for these classes and some static maps that will also be checked in (but are not included in this PR).
The idea is that these codes don't change often, and so we don't need to generate them on every build, but we would like to be able to update them easily in the future if new data becomes available. If the existing data disappears or becomes unusable, we can maintain the checked-in data structure by hand if necessary, and still be able to generate the code.
This PR only contains the code generator, not the classes themselves. In another follow-on PR, I'll run the generator and check in the output of the generator.
